According to the built-in wine debugger it was > 0x00495000 EntryPoint in war3: pushl %eax which does do a write, but to %esp (which is 7f9eff0c according to the dump, and which is unlikely to have taken a fault, since it's almost 256 bytes off the end of a page in the stack area). Alistair, if you can do a "git bisect" on this one, that would help. Unless Andi goes "Duh!". Linus
